中国东北汉族人群解偶联蛋白3基因-55C/T多态性与2型糖尿病相关性研究
Zhongguo shiyan zhenduanxue, 2010 目的探讨解偶联蛋白3（uncoupling protein 3,UCP3）基因-55C→T变异与中国东北地区2型糖尿病的关系。方法用聚合酶链反应-限制性片段长度多态性检测100例2型糖尿病患者（男/女为58/42）及113名糖耐量正常者（男/女为56/57）UCP3基因-55C→T变异的基因型。结果 2型糖尿病组与正常对照组三种基因型频率及等位基因频率分布差异均有显著性意义,P值分别为0.027和0.003,两组间携带T的基因型（CT+TT）频率差异有显著意义（P=0.008 ...

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition
Functional Ecology, Volume 40, Issue 8, Page 2548-2559, August 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

MN基因定型在恶性血液病异基因造血干细胞移植植活证据检测中的临床研究
Zhongguo shiyan zhenduanxue, 2011 目的探讨MN基因型定型在恶性血液病异基因造血干细胞移植植活证据检测中简单可行的方法。回顾性分析了10例患者恶性血液病异基因造血干细胞移植的临床资料。方法分别采取受者和供者移植前及移植后14天及365天的血液标本,根据已知基因序列设计合成引物,采取PCR-SSP的方法检测方法的检测受者和供者移植后的基因型和基因亚型。结果 10例患者MN为5例,MM为3例、NN为2例或MGMG2例,MTMT1例,MGMT6例,MTN1例。与血清学结果完全吻合。显示两组样本的表型与基因型吻合很好,资料的说明性较好（P>0 ...

Functional Ecology, Volume 40, Issue 8, Page 2590-2601, August 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

四川大学学报. 自然科学版, 2015 构建了麻疯树(Jatropha curcas)一个新的ERF类转录因子基因RNA干扰(RNAi)载体,并将之转入过表达JcERF1基因烟草体内,得到了RNA干扰型烟草.利用实时荧光定量PCR(QPCR)检测了JcERF1基因的表达量,发现该基因在干扰型烟草中表达量明显降低.通过野生型、过表达型和干扰型烟草的种子萌发实验和高盐胁迫实验发现:与过表达型烟草相比,干扰型烟草的抗盐能力明显降低,且干扰型烟草的游离脯氨酸和可溶性糖含量在高盐处理后上升的幅度明显低于过表达型烟草 ...

Inferring alternative ecosystem states with field survey data
Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2256-2276, August 2026.Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...
